Title: Video transmission and control system utilizing internal telephone lines
Inventor: GOODMAN DAVID D
IPC: H04L12/28
Filed: 1990-07-10
Granted: 1994-06-21
Abstract: ABSTRACT OF THE DISCLOSURE    A  video  transmission  system  for  facilitating transmission of video and control signals, particularly infrared  remote  control  signals,  between  different locations  in  a  residence  using  existing  telephone wiring.   Simultaneous transmission of signals of both types over active telephone lines is possible without interference with telephone communications.  Transmis-sion succeeds without requiring special treatement of the video signals beyond RF conversion, despite signal attenuation inherent in transmission over the telephone line media.  Two or more video sources may be tied into the system,  and selected as desired.   Remote control signals generated in one room may be utilized without requiring a clear line of  sight between the remote control device and the receiver.

Granted: 2002-01-15
Abstract: An auditory prosthesis, and method, which is able to adapt better to filter out a selected unwanted portion of the auditory input signal by relying on a human activation, such as activation by the user, who knows by listening when the auditory environment contains only, or mostly only, the selected unwanted portion of the auditory input signal. This person may then activate the adaptive filter of the auditory prosthesis. The adaptive filter then utilizes the then current auditory environment as a noise reference on which to adapt. An auditory prosthesis which is adapted to receive environmental sound containing a selected auditory component and which is adapted to supply an auditory stimulus which is perceptible to a user. A transducer is adapted to receive the environmental sound and convert the environmental sound into an electrical input signal. The electrical input signal contains a selected electrical component corresponding to the selected auditory component in the environmental sound. An adaptive filter receives the electrical input signal and provides a filtered signal. The adaptive filter has adaptable filtering characteristics based upon a reference. The adaptive filter is operable in response to activation by the user to adapt the filtering characteristics using the electrical input signal as the reference to determine the filtering characteristics required to filter the selected electrical component from the electrical input signal. The filtered signal is received and converted to the auditory stimulus. Rapid adaption by the filter in response to activation by the user and slow adaption when not activated may be used.

Abstract: A method and system for synchronising directories containing information about computer mail users is provided. In a preferred embodiment , a computer mail facility synchronizes a user directory stored in a respondin g directory node with a more current user directory stored in an originating directory node. The facility first acquires in the originating directory nod e one or more directory update transactions for updating the contents of the user directory stored in the originating directory node. The facility assigns a consecutive sequence number to each transaction indicating the order of acquisition. The facility then updates the contents of the user directory stored in the originating directory node by processing the transactions in the order o f their sequence numbers. At a later time, the facility selects a series of the transactions for transmission to the responding directory node. The sequence number of the first directory update transaction in the series is consecutiv e to an originating directory node synchronization number that stores the sequence number of a last confirmed transmitted directory update transaction. Also, t he assigned sequence numbers of all directory update transactions in the series are consecutive. After selecting the series of transactions, the facility transmits transactions of the series from the originating directory node to the responding directory node. The facility receives the transactions of the series in the responding directory node, then transmits a confirmation message indicating the largest consecutive sequence number of the received directory update transactions from the responding directory node to the originating directory node. Upon receiving the confirmation message in the originating directory node, the facility sets the originating directory node synchronization numbe r to the sequence number indicated by the confirmation message.

Abstract: A valve which includes signal generating means for generating a signal representing a pressure drop occurring within a vehicle tire. The valve includes an absolute pressure sensor coupled to measure the pressure within the tire. A microprocessor is provided which upon activation following operation of the valve stores a value of the electric pressure signal from the pressure sensor in a memory. During operation of the vehicle, the stored reference electric pressure signal is compared with periodic measurements of pressure within the tire. The transmitter is activated at periodic intervals, whenever a given ratio between the compared values and a threshold value exceeds an upper or a lower limit. The system is activated by an acceleration sensor which can detect when the vehicle is moving, thus avoiding power consumption when the vehicle is stopped.
